ResNets solve is the famous known vanishing gradient.
Vanishing Gradient Problem occurs when we try to train a Neural Network model using Gradient based optimization techniques.
As more layers using certain activation functions are added to neural networks, the gradients of the loss function approaches zero, making the network hard to train.
Image is the sigmoid function and its derivative. Note how when the inputs of the sigmoid function becomes larger or smaller (when |x| becomes bigger), the derivative becomes close to zero.

Thanks to Google’s satellites, Street View vehicles, and user-generated corrections, Google’s geographical coverage is considered the best.
2.Multiple style options.
The JSON-like syntax used by Google Maps is immediately loaded along with a map. You can manage the visibility, color, and opacity of all map elements.
3.Street View.
Street View is a feature that provides interactive panoramas from different positions along lots of streets around the world. This feature can visualize Keyhole Markup Language (KML) and GeoRSS data on the map.
Mapbox Maps SDKs are open-source. Mapbox shares their code on GitHub so it can always be seen, analyzed, and improved.
3.Integration with PubNub.
Mapbox partners with PubNub, which offers infrastructure-as-a-service for live data streaming, builds dynamic map visualizations from real-time data, and incorporates functionality like asset tracking, geocoding, and heatmaps.
4.Mapbox AR.
The Mapbox Maps SDK for Unity allows for building location-based experiences using points of interest (POIs) all over the world. You can add locations using drag-and-drop maps and POIs, 3D buildings and terrain, place-based AR, and more.
5.Offline maps.
There’s no offline mode with the Google Maps API. More precisely, offline mode is available in the branded Google Maps app.
The bad points of Mapbox.
1.Relatively weak coverage.
There are many places where Google has better coverage than OSM based services.
